To all Be i own that I, CHRISTOPHER BYRNE, is attached thereto. Directly below the lamp of Con ut, in the county of Ashtabula and is' a catch basin or cup, E, Fig. 3, a detached State a hio, have invented a new and Imviewof which is shown in Fig. 5. Said basin prove ocomotive Head-Light; and I do is suspended by a dishing flange, a, in a venhereb e'clare that the following is a full, 'tilator, I, as shown in Fig. 3, in which it will clear, exact description of the same, refbe seen that between the catch-basin and venerence ing had to the accompanying drawtilator there is an annular space, d.

Said door is made to shut tight by minat by a deflecting head or button, 0. Of a groove, 0, made in and around the edge of saidl F is the chimney, the upper end of the doorway. A corresponding tongue or rib, which held steadily by a stay, Gr, having 6, is formed around the edge of the door, which, finger for clasping the chimney. The when shut, is received into the groove, as

h e chimney is secured to the lamp by shown in Fig. 3.

sisting of a perforated plate, a, Fig. It will be seen that the lamp, oil-reservoir, oh the chimney stands, and a crown, and reflector above described are secured to a .d to a sleeve, 0', fitting on over the platform or slide, 0, Fig. 2, slid into the case or body A upon the floor Pthereof, and which is retained therein by tongues and 'cleatsl, Fig. 2. In thus securing the lamp, 850., to the slide, the lamp can be withdrawn from the case for cleaning, &c.

A are springs, on which the reflectoris partially supported, and thereby relieved from being too much jarred and jolted by the locomotive. In each side of the head-light are a.

pair of colored glasses, B C, Fig. 2, which may be closed by the slides D and E.

To prevent a rush and undue pressure of air into the chamber or ventilator through the perforations is the purpose of the annular slanting flange or shield t, which checks the direct pressure and currents of air from the perforations and deflects them downward, so that the air passes under the edge of the flange, thereby producing a uniform and steady supply of air to the lamp directly through the perforated lower part F, and through the perforations from the body of the head-light, which is ventilated by a perforated plate, G, covering the ventilatingchamber I immediately around the base of the lamp, as shown in Fig. 3.

It will be observed that the deflector is supported in position by adjusting-screws H, projecting from the frame I and screwed into the ears J of the reflector. By means of the adjusting-screws the reflector can be moved toward or away from the lamp, thereby concentrating the light upon the track near the engine, or distant therefrom, more or less, at the will of the engineer, as he may require to illuminate the road far ahead or near by.

In defining more clearly my invention, I

would state that I am aware that it is not'new to employ a plain form of reflector in the rear of the lamp, and that the general arrangement of the lamp-burner, drip-cup,'and ventilator is also old. I therefore only claim the peculiar construction and arrangement of such parts, as shown and described.

What I claim as new is 1. In locomotive head-lights, the concave reflector B, secured in position by adjustingscrews H, and partially supported on springs A, arranged wholly in the rear of the lamp, substantially as described, and for the purpose set forth. a

2. The ventilator I, damper m, and shield t, as arranged in relation to and in combination with the lamp and body A of a locomotive head-light, substantially as described, and for the purpose specified.

3. In combination with the ventilator land lamp, the drip-cup H, provided with air-openings e and conductors J, in the manner set forth, and for the purpose specified.

4. In locomotive head-lights, a dome consisting of the perforated flue K, deflectors L, cap N, and shields M, arranged in relation to each other substantially as described, andfor the purpose setforth.

5. In locomotive head-lights, the door 0, provided with a tongue or rib, z, arranged in relation to the groove 0 of the doorway of the body A as to fit thereinon shutting the door, as and for the purpose specified.
